Unlike the band's previous yearly studio albums, the conception and release of World World World spanned almost two years. The album's lead single, "Aru Machi no Gunjō," was released on November 2006, and after spending nearly the entirety of 2007 touring and performing at festivals, AKFG ended the year with the release of its second single, "After Dark." The third and final single, "Korogaru Iwa, Kimi ni Asa ga Furu" was released a month prior to the album's drop.
Despite the significant time-span between the releases, both the LP and all three singles were well received. Alongside World World World debuting at number one on the Oricon chart, AKFG was once more selected to produce the opening theme for yet another highly popular anime series, with "After Dark" being chosen as the seventh opening of Bleach.
